Notes: AUD: Australian dollars, 2019 values; B: billions; BCR: benefit–cost ratio; BMI: body mass index; CUA: cost–utility analysis; HALYs: health-adjusted life years gained; HSR: Health Star Rating; ICER: incremental cost–effectiveness ratio; m: meters; kg: kilograms; M: millions; N/A: not applicable; NPV: net present value; UI: uncertainty interval. *Negative net costs represent savings. Dominant means that the intervention produces cost-savings and health gains compared to the no intervention comparator. β ICER below AUD 50,000 per HALY gain.
